Are you referring to the kind of metal tanks with roofs that change height?
Or are you thinking of some kind of storage in giant low pressure balloons/gas bladders, on the ground, that are anchored to the ground? Giant low ground mounted pressure balloons may be a cost effective way to store huge amounts of H2. It certainly is possible to build such things. Position them near network bottlenecks. (I guess they could also be tethered, allowed to be kept aloft, and simultaneously used as platforms for aerial wind turbines similar to some turbines that have been proposed in the past. This would reduce the variable working capacity of the balloons, but would free up space on the ground.)
